FAST STORM MOTION ALSO ENHANCES WIND THREAT. HOWEVER, THETA-E NOT IMPRESSIVE BETWEEN SFC AND LVLS UP TO 600MB. LAPSE RATES STEEPEN CONSIDERABLY IN ASSOCIATION WITH MID LEVEL COOLING AND APPROACHING UPR TROF. BEST INSTABILITY EXPECTED TO BE ACROSS NRN AREAS WHERE MU CAPES EXPECTED TO RANGE FROM 500-1300J/KG EARLY THIS EVENING. DEW POINTS ARE CURRENTLY LOW BUT 06/12Z NAM12 AND LATEST RUC SHOWS DEW POINTS INCREASING IN NARROW RIBBON AHEAD OF FRONT TO UPPER 50S.
